Definitions
- the present disclosure relates generally to apparatuses, systems and methods for affecting movement of a land vehicle.
- the present disclosure relates to apparatuses, systems and methods for selectively affecting the movement of a motor vehicle including, for example, deterring, restraining and/or immobilizing a motor vehicle by entangling one or more tires on the vehicle.
- Conventional devices for slowing, disabling, immobilizing and/or restricting the movement of a land vehicle include barriers, tire spike strips, caltrops, snares and electrical system disabling devices.
- conventional spike strips include spikes projecting upwardly from an elongated base structure that is stored as either a rolled up device or an accordion type device. These conventional spike strips are unfurled or unfolded and placed on a road in anticipation that an approaching target vehicle will drive over the spike strip.
- Successfully placing a conventional spike strip in the path of a target vehicle results in one or more tires of the target vehicle being impaled by the spike(s), thereby deflating the tire(s). This can make it difficult for the driver to maintain control of the vehicle and can result in personal injury and/or property damage.
- Conventional devices may be used by first response personnel, law enforcement personnel, armed forces personnel or other security personnel. It is frequently the case that these personnel must remain in close proximity when deploying these devices.
- a conventional method of deploying a spike strip is to have the personnel toss the spike strip in the path of an approaching target vehicle. This conventional method places the security personnel at risk insofar as the driver of the target vehicle may try to run down the security personnel or the driver may lose control of the target vehicle while attempting to maneuver around the spike strip and hit the security personnel.
- rapidly deflating only one of the steering tires may cause a target vehicle to careen wildly and possibly strike nearby security personnel, bystanders, or structures.

- Embodiments in accordance with the present disclosure are set forth in the following text to provide a thorough understanding and enabling description of a number of particular embodiments. Numerous specific details of various embodiments are described below with reference to immobilization devices for vehicles having tires engaging a paved surface, but embodiments can be used with other ground engaging features (e.g., tracks) and with other types of terrain (e.g., dirt, gravel, and other non-paved surfaces). In some instances, well-known structures or operations are not shown, or are not described in detail to avoid obscuring aspects of the inventive subject matter associated with the accompanying disclosure.
- a wheel may generically refer to a wheel including a solid rubber or pneumatic tire mounted around its periphery. A person skilled in the art will understand, however, that the invention may have additional embodiments, or that the invention may be practiced without one or more of the specific details of the embodiments as shown and described.
- aspects of the present invention are generally directed to an apparatus for affecting movement of a vehicle that includes a rotating wheel.
- One aspect of embodiments is directed toward an apparatus including a housing configured to be positioned in a path of the vehicle such that the rotating wheel crosses the housing, a membrane or snare having a contracted arrangement and an extended arrangement, and a snagging member coupled to the snare.
- the snare is disposed in the housing in the contracted arrangement and is configured to wrap around the wheel in the extended arrangement.
- the snagging member is configured to snag the wheel when the snare is in the contracted arrangement.

- the second snare is disposed in the housing in its contracted arrangement and is configured to wrap around the second wheel in its extended arrangement.
- Individual sets of snags are configured to extract an individual snare from the housing between the contracted and extended arrangements, and individual snags are generally shielded by the housing in the stowed arrangement and are exposed in the deployed arrangement.
- Yet other aspects of the present invention are generally directed to a method for affecting movement of a vehicle that includes a rotating wheel.
- One aspect of embodiments includes positioning a housing in a path of the vehicle such that the rotating wheel crosses or traverses the housing, enclosing a snare in the housing and coupling a snagging member to the snare, exposing the snagging member with respect to the housing, engaging the snagging member with the rotating wheel, and entangling the snare around the rotating wheel so as to bring the target vehicle to a stop.
- Certain embodiments according to the present disclosure include a vehicle restraint system that entangles the wheels of a selected moving vehicle to deter, restrain, or immobilize the vehicle as it travels along a path.
- the vehicle restraint system includes a housing that has been installed or otherwise placed in the ground or in the path of a targeted vehicle, e.g., on a roadway.
- the front wheels of the vehicle become snagged and a snare is dispensed from the housing to wrap around the front wheels during rotation of the front wheels
- the back wheels of the vehicle become snagged and a second snare is dispensed from the housing that wraps around the back wheels during rotation of the back wheels.
- Certain other embodiments according to the present disclosure include the housing configured as a protuberance that extends at least in part laterally across the width of a roadway.
- a snare is dispensed from the housing and may include netting and/or a web-like material that is of sufficient strength to be twisted around vehicle tires to ensnare or entangle the vehicle tires.
- the housing may contain a first and/or second netting sub-system for engaging front and/or rear vehicle tires of an oncoming target vehicle. When the front tires of the target vehicle are driven over the housing, the netting/web-like material is dispensed from the first netting sub-system within the housing to engage with the front vehicle tires and ensnare or entangle the front tires during tire rotation.
- the vehicle immobilizing device may include components to ensnare or entangle either the front or rear wheels of the target vehicle depending on the vehicle wheel configuration, e.g., front, rear, or other wheel drive.
- the housing may be configured as a road protuberance that slightly bulges above a road surface, e.g., a "speed bump” (also referred to as a "speed hump,” “road hump” or “sleeping policeman”).
- a "speed bump” also referred to as a "speed hump,” “road hump” or “sleeping policeman”
- the housing may be configured to be installed in a cut-away in a road and seated flush with the pathway. In either manner, the housing may be configured such that its capability for vehicle immobilization is concealed from the driver of an oncoming vehicle.
- Certain other embodiments according to the present disclosure include a system that can be selectively armed and disarmed. When disarmed, the system is placed into a "sleep" or “deactivated” mode in which vehicles may be driven over the housing without consequence, much like a conventional speed bump. When the system is armed, however, the system will snag, for example, the tires of the next vehicle that is driven across the housing.
- the system can be selectively armed and disarmed remotely via wired or wireless communication from a vehicle sensor and/or an operator controlled device.
- Certain other embodiments according to the present disclosure include a housing having two openings, through which the first and second netting/web-like material is dispensed, e.g., one snare per opening.
- the netting/web-like material may include a section in which barbs, spikes, nails, staples, adhesive patches or other types of snagging members are affixed to or integrated with the material to engage a vehicle wheel(s) that are driven across the openings in the housing.
- the snagging members for the first netting/web-like material are positioned so as to be exposed, e.g., protrude outward from the upper surface of the housing, as the front vehicle wheels are being driven across a first opening in the upper housing. This causes the front wheels of the vehicle to become snagged. As the front wheels continue to rotate, the first netting/web-like material is pulled by the rotating wheel to extract the material from within the housing and become wrapped around the front rotating wheels.
- the snagging members for the second netting/web-like material are positioned so as to be exposed, e.g., protrude outward from the upper surface of the housing, as the rear vehicle wheels are being driven across a second opening in the upper housing, thereby causing the rear wheels to become snagged by the spikes/barbs, causing the second netting/web-like material to be dispensed from the housing and become entangled around the rear rotating wheels.
- the vehicle immobilizing system may include netting/web-like material for engaging with only the front set of wheels, or only the rear set of wheels.
- the netting/web-like material may be sized and configured to ensnare or entangle both the front and rear wheels on one side of the vehicle.
- the housing may be configured such that both sets are dispensed serially from the same opening.
- a first netting/web-like material may be employed for the front wheels, whereas a different netting/web-like material may be employed for the rear wheels.
- Figures 1A and 1 B are schematic views illustrating different arrangements of a vehicle immobilizing device 100 according to an embodiment of the present disclosure.

- the second member 860 moves parallel to the longitudinal axis A relative to the first member 850 and relative to the third member 870. This relative movement of the second member 860 uncovers the spikes 6 beneath slots 876 in the third member 870. Also, the first member 850 moves perpendicular to the longitudinal axis A relative to the second member 860 and relative to the third member 870.

- Figure 16A shows an example of certain embodiments according to the present disclosure that integrate the tethers 702 into the construction of a net 700'.
- the chords used to make the net 700' may extend beyond the leading edge 704a of the net 700' and couple to individual spikes 6, or the spikes 6 may be integrated into the leading edge 704a of the net 700 as shown, for example, in Figure 16A.
- Figure 16B shows an example of certain other embodiments according to the present disclosure that omit separate tethers 702 and directly couple the spikes 6 to a net 700", preferably to the chords used to make the net 700".
- the first strip 710 may include a plurality of segments (e.g., two segments 710a and 710b are shown in Figure 16B) such that at least one break 710c in the first strip 710 will be positioned within the wheel track of the target vehicle.
- a segmented first strip 710 may be used in certain embodiments according to the present disclosure including, e.g., the nets 700, 700' or 700".
- the net 700 may be constructed to satisfy different performance requirements.

Examples of different performance requirements may include stopping a first vehicle weighing up to 6,000 pounds and traveling at up to 50 miles per hour, or stopping a second vehicle weighing up to 40,000 pounds and traveling at up to 30 miles per hour. The performance requirement to stop the second vehicle is approximately four times the performance requirement to stop the first vehicle.
- FIG 17 is a detail view of an embodiment according to the present disclosure of a cord 750 that may be used to construct the snaring member of Figure 15 and/or the tether 702 of Figure 16.
- the cord 750 may be constructed of fibers or filaments 752 that may be twisted together to produce a yarn 754.
- Certain embodiments according to the present disclosure include twisting the filaments 752 in a right laid direction also known as a "Z-twist.”
- a plurality of yarns 754 (three are shown in Figure 17) may be twisted together to produce a strand 756.
- Certain embodiments according to the present disclosure include twisting the yarns 754 in a left laid direction also known as an "S-twist.”
- a plurality of strands 756 (three are shown in Figure 17) may be twisted together to produce the cord 750.
- Certain embodiments according to the present disclosure include twisting the strands 756 in the right laid direction, i.e., with the "Z-twist.”
- Other embodiments according to the present disclosure may include more or less than three yarns 754, more or less than three strands 756, and/or different combinations of S and Z twists.
- Other techniques, e.g., braiding rather than twisting, may also be used in the construction of the cord 750.
- the cord 750 may include a hybrid construction in certain embodiments according to the present disclosure.
- the filaments 752 may include a plurality of materials, a variety of materials may be used for individual yarns 754, a variety of materials may be used for individual strands 756, and/or a combination of each of these may be included in the construction of the cord 750. Examples of suitable materials and some of their characteristics are described in Table A.
- the cord size specified in Table A is in inches and the strength specified in Table A refers to the tensile strength in pounds.
- the abrasion and cost characteristics are relative to the materials specified in Table A.
- Certain embodiments according to the present disclosure may also use larger or smaller size cords, e.g., #96 size cord which has a diameter of approximately 0.136 inch.
- a mixture of fiber, yarn, strand or cord materials according to certain embodiments of the present disclosure may be used to construct a net 700 having a set of characteristics, e.g., performance, weight, abrasion resistance and cost, that are different than using a homogenous fiber, yarn, strand and cord for the entire net 700. Accordingly, the inventors have discovered that a variety of nets 700 may be used to customize the deployment module 540 for different implementations, and that other features of the immobilizing device 500, e.g., segments 502 and 560, may share at least some commonality.
- a method according to embodiments of the present disclosure for implementing a vehicle immobilizing device will now be described.
- a vehicle immobilizing device 100, 200, 300 or 400 can be positioned in a "decision zone" that can be positioned prior to a "stop zone” at a checkpoint, an entry gate, or any other location at which it is desirable to screen vehicle traffic.
- a vehicle approaching the location would typically slow to allow security personnel manning the location to have an opportunity to investigate the vehicle as it comes to a stop in the decision zone.
- a friendly vehicle is typically allowed to pass through the decision zone and bypass the stop zone.
- the security personnel can selectively arm the vehicle immobilizing device 100, 200, 300 or 400 such that prior to the vehicle rolling over, for example, the vehicle immobilizing device 100, a sensor, e.g., sensor 410, will have activated the actuator mechanism 570 and deployed the spikes 6.
- a sensor e.g., sensor 410
- the spikes 6 penetrate into and latch onto the leading tires of the vehicle.
- the tires draw the snaring member 9 out of the speed-bump 1 and the snaring member 9 can twist and become entangled around the rotating tires.
- the spikes 7 are deployed out of the speed-bump 1 and penetrate into and latch onto the trailing tires of the vehicle.
- the snaring member 5 is drawn out of the speed-bump 1 and can twist and become entangled around the rotating trailing tires. The entangled snaring members then will continue to twist until leverage against the under carriage of the vehicle brings the tires to a stop. Accordingly, the vehicle can be slowed and stopped in a controlled and non-lethal manner.
- other embodiments can include various features for deploying the trailing tire spikes.
- the spikes 7 can be deployed after a time period that is less than the time it takes between the leading and trailing tires rolling over one of the vehicle immobilizing devices 100, 200, 300 or 400.
- a smart logic timing device can be used to deploy the spikes 7 after a time period, e.g., not more than approximately 100 milliseconds, following deployment of the spikes 6.
- the trailing tire spikes can also be deployed upon the leading tire withdrawing a length of a snaring member, or based on contact of the trailing tires with the vehicle immobilizing device 100, 200, 300 or 400.
- Other techniques are suitable so long as the trailing tire spikes are deployed after the leading tire has rolled over the vehicle immobilizing device and before the trailing tire rolls on the vehicle immobilizing device.
- still other embodiments of can deploy the spikes by deflating or otherwise compressing the speed-bump to expose the spikes.
- the leading tires could deflate a first portion of a vehicle immobilizing device 100, for example, to expose and engage the spikes 6, and the trailing tires could subsequently deflate a second portion of the vehicle immobilizing device 100 to expose and engage the spikes 7.
- yet other embodiments can include a vehicle immobilizing device that is packaged in the form of or housed in a portable speed-bump that is meant to be positioned in the path of traffic at a selective location or pathway of traffic.
- the speed bump can also be used to slow down traffic and, unbeknownst to an operator of a particular vehicle, the speed bump can also selectively immobilize the particular vehicle with minimal damage and risk to the vehicle occupants.
- a vehicle immobilizing device can be remotely armed in anticipation of a particular vehicle. As the particular vehicle approaches the speed bump, the barbed spikes can be deployed from the speed bump to initiate a series of snaring events. Else, the vehicle immobilizing device can also be remotely disarmed prior to the vehicle reaching the speed-bump. Once disarmed, the vehicle immobilizing device can serve back as a conventional speed-bump for merely slowing traffic. [0102] According to the present disclosure, still further embodiments of the vehicle immobilizing device can also be permanently or semi-permanently housed bellow the road grade on a drive way or pathway and remotely or directly activated in according to an aforementioned manner. According to other embodiments of the present disclosure, individual snaring members can be launched, e.g., pyrotechnically, from a housing toward the tires of a vehicle.
- spikes can be coupled to snaring members proximal to edges of the snaring members, at net joints (e.g., knots) of the snaring members, or distributed over the surface of the snaring members.
- a backing or doubling layer can be used to couple spikes to structural strands of a snaring member.
- spikes can be spring loaded or otherwise biased with respect to a housing of the speed-bump. Accordingly, releasing the spring or biasing element with an actuator can allow the spikes to be deployed.
- a kit for field refurbishing the vehicle immobilizing device may contain a deployment module and/or a replacement energy source for activating the actuator mechanism.
- Additional embodiments according to the present disclosure can include batteries or solar cells to provide electrical power for the vehicle immobilizing device, indicators for the state of the battery charge and whether the vehicle immobilizing device has been armed, self diagnostics to evaluate the operability of the vehicle immobilizing device, and wireless or wired controllers for remotely arming of the vehicle immobilizing device from a suitable distance.
- embodiments according to the present disclosure can include reinforcements to withstand heavy vehicles passing over the vehicle immobilizing device or can include features for protecting the vehicle immobilizing device from exposure to various environments such as water or sand.
- embodiments according to the present disclosure can be sized in accordance with the terrain and intended implementation of the vehicle immobilizing device, e.g., extending across a single traffic lane or more than one traffic lane.
